Contribution à la critique de l'économie politique

The Grundrisse der Kritik der Politischen Ökonomie (Foundations of a Critique of Political Economy) is an unfinished manuscript by the German philosopher Karl Marx. The series of seven notebooks was rough-drafted by Marx, chiefly for purposes of self-clarification, during the winter of 1857–8. Left aside by Marx in 1858, it remained unpublished until 1939.
